Hello,

I'm trying to download several files in a list one after another, I used 
DownloadFileAsyn for asynchronous download, the problem is I always get this 
error message "Web Client does not support concurrent I/O operations" 
however there is nothing concurrent in what I do, as I wait for one download 
to complete and in the DownloadFileCompleted WebClient event I start a new 
download using the DownloadFileAsync.

Thanks

You have to add a unique object to each async call.
